Most geologists say an earthquake of 5.0 or less on the Richter Scale about every five years or so would not be uncommon considering the geology of the state. So far Louisiana has been lucky and there have been no major earthquakes reported in the state since they started tracking things like that.

However, an earthquake in the state may not be as big of a concern as an earthquake north of the state in Southern Missouri or Northern Arkansas along the New Madrid Fault. Geologists believe a major earthquake along that faultline could and will eventually happen. Should that occur the push of water down the Mississippi River could create catastrophic flooding all the way to the Gulf of Mexico.
